I finally got around replacing two PC dual actinic lights and one 150W HQI 10K bulb yesterday. I replaced the dual arctinic from 460 to a 420 nm spectrum, and the Coralife DQI from 10K to XM 14K bulb. My wife's first reaction when she saw the new lighting was "WOW." I had to admit, even I was very impressed with it. The new actinic light with a different spectrum actually made the lighting in the tank even better. Everything seems to stand out more. Once the HQI light turned on, the tank no longer looked washed out like it did before. What amazes me were how much more vibrant everything in the tank looks. The acan lord that I got from Steve Outlaw, my God, what a difference the different spectrum lighting makes. I am extremely happy with it. Now, I just need to take some pictures and post it for you guys to see.
